I picked up a set of these the other day and the combination of crappy wiring digrams and my lack of experience with wiring isn't going well. Here is my question, from the relay they have 1 red wire coming from the battery, 1 split black wire going to the lights, 1 blue wire as the ground from the relay, and one yellow wire going to the dash for the switch. Now from the switch they show wire going into the factory wiring for the high beams which I am not going to do. The question is this leaves only 1 wire going from the relay to the switch, does this make a circuit? Also on the switch there are 2 other blades one of which is marked for a ground, should I make a ground from the switch to the body even though the instructions don't show it? Hope that wasn't to confusing, any input is greatlly appreciated. BTW I got the 500s because that was the largest light I could put on the bull bar with an 8274 winch without the getting in the way of the headlights.
